Citrix XenServer 6.5 Released

So, what’s new in XenServer 6.5? A lot of good stuff!
  • All 64-bit
  • Massive performance improvements
  • 50% increase in GPU density
  • The return of the popular Workload Balancing (WLB) appliance
  • Numerous usability enhancements
So, let’s talk about some of these performance enhancements.  While XenServer has long been known for it’s world-class compute performance, we realized that more and work workloads are now becoming I/O bound.  Thus, the team put massive effort into improving the data path through the networking and storage systems.  Here are some sample benchmarks comparing the performance of XenServer 6.5 vs. XenServer 6.2 (the last major release).

Who should be interested in XenServer 6.5?  Firstly, anyone who’s using XenServer today will find this a major step up.  Upgrade today and see the difference.  Who else should be interested?  Are you building a cloud?  Xen project is the most popular hypervisor for the cloud and XenServer is the most popular, commercial distribution for Xen project.  XenServer is an efficient, cost-effective and battle-tested choice for your cloud?
Are you running XenApp or XenDesktop?  XenServer is your best choice for those environments as well.  Not only is XenServer included for free (saving you substantial cost), but you get a single stop for support.  Perhaps even more importantly the XenServer and XenDesktop teams work together closely to bring you world’s-first access to new technology like vGPU-enabled, remote desktops.
Are your virtualizing Enterprise computing workloads?  XenServer is a high-performance, cost-effective, easy-to-use option for your needs.  With no separate management server required for features like live-migration and HA, it’s can’t be easier to get started.  And, with years of experience running both Linux and Windows workloads, it’s a great choice no matter which OS you’re virtualizing.

1)       Table depicting support for various SSL/TLS versions on different Windows OS   2)       SMTP – key piece of Exchange server infrastructure – support for TLS 1.1 and 1.2 were added in Exchange Server 2013 CU8 and Exchange Server 2010 SP3 RU9. This means if you want to add support for the latest ciphers and TLS versions, you may need to apply an update. 3)        Disable SSL  3.0 on all windows exchange servers Steps to disable support for the SSL 3.0 protocol on Windows by following these steps: ·          Click Start, click Run, type regedt32 or type regedit, and then click OK. ·          In Registry Editor, locate the following registry key: ·          HKey_Local_Machine\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Server ·          Note If the complete registry key path does not exist, you can create it by expanding the available keys and using the New -> Key opti

HP 3PAR storage Commands to troubleshoot performance issues

The quick reference guide below will help diagnose and rule out some common issues experienced in the 3PAR arrays.  CLI COMMAND – “STATVLUN” measures the round trip time of an IO as seen by the system. Running STATVLUN in the following order should lead to the resolution of a few performance issues: 1)      “statvlun –ni”   – The STATVLUN command without any switches will show the round trip time of IO on each path for exported Virtual Volumes. This is helpful to determine if there is a multipathing issue. The “-ni” flag will eliminate any inactive volumes. 2)      “statvlun –vvsum –ni –rw”   This will show you the round trip time of the IO to each volume with the paths condensed for consolidated reporting.  This is great to see an overall picture of what is going on The “-rw” flag will break the IO down into Reads & Writes. 3)      “statvlun –hostsum –ni –rw”   The output of this command will show you the round trip time of the IO organized to the host le
